IT'S EZ AND QUICK TO INSTALL, I KEEP MY OLD "PLATE" W/ MY POINTS UNDER MY BACK SEAT, JUST IN CASE MY "IGNITOR SYSTEM" WERE TO FAIL.....I COULD HAVE IT BACK TOGETHER AND TEMPORARILY TIMED BY EAR IN LESS THAN 5 MINUTES

READ THE INSTRUCTIONS CONCERNING THE NEED FOR A BALLAST RESISTOR OR RESISTANCE WIRE....MINE ORIGINALLY USED A BALLAST RESISTOR USING POINTS, I LEFT IT ON THERE, BUT JUST "PIGGYBACKED" THE OTHER TERMINAL, SHOULD I NEED TO REVERT BACK, I WILL MOVE THE WIRE BACK TO IT'S ORIGINAL TERMINAL
